摘要: The present invention provides an improved nucleic acid hybridization process employing a modified oligonucleotide probe comprising naturally occurring nucleotide bases. At least one nucleotide in the modified oligonucleotide is artificially mismatched relative to the control nucleic acid in addition to any mismatches arising from a variant nucleic acid target containing a sequence variation. The artificial mismatch and the sequence variation positions are separated from one another on the oligonucleotide by six to nine nucleotide positions.

摘要: The present invention provides a microarray for detecting a genotype at a polymorphic site in a plurality of nucleic acid samples, comprising a first set of nucleic acid fragments derived from the samples and a second set of nucleic acid fragments derived from a plurality of references immobilized thereon. The invention also provides a microarray comprising a set of nucleic acid fragments immobilized on the surface of the microarray, wherein the nucleic acid fragments are derived from the samples by amplifying a region in the sample containing the polymorphism through asymmetric PCR amplification. Methods of using and making the microarrays are also provided.
